Description
Technical field
The present invention relates to petroleum pipeline and sewage conduit cleaning field.It is more particularly related to a kind of using high
The field of pressure water jet technology on petroleum pipeline and sewage conduit cleaning.
Background technology
High-pressure water jet clean technologies refer to water is forced into more than hundreds of atmospheric pressure by high pressure water generating device, then
Fine " water jet " of high speed is converted to by the injection apparatus with tiny aperture.The speed of this " water jet " typically all exists
More than one times of Mach number, with huge blow energy, different types of task can be completed.High-pressure water jet clean technologies are
The high-tech cleaning technique risen in the world in recent years.Cleaning by High Pressure Water Jet is with cleaning cost is low, speed is fast, clear
Net rate is high, do not damage cleaned material, have a wide range of application, it is free from environmental pollution the features such as.Since the incoming China of the mid-80, by
The generally approval of industrial quarters has gradually been obtained with paying attention to.The cleaning technique used in traditional washing and cleaning operation has machine drilling clear
Wash, the cleaning of steam clean, Chemical cleaning, ultrasonic wave and tens kinds of forms such as water jet cleaning.Up to the present, water under high pressure
Jet flow cleaning has become the main flow cleaning technique of western developed country, has accounted for more than the 80% of the cleaning industry market share,
The U.S., Cleaning by High Pressure Water Jet has accounted for the 90% of cleaning industry." Cleaning by High Pressure Water Jet belongs to physical cleaning method, with biography
The artificial of system, mechanical cleaning and Chemical cleaning are compared, and are had the following advantages:1. the pressure of water jet can be adjusted easily with flow
Section, thus the matrix of cleaned material will not be damaged.2. Cleaning by High Pressure Water Jet does not result in secondary pollution, such as without spy after cleaning
It is different to require, it is not necessary to carry out clean processing.3. shape and baroque object are washed, can be in narrow space or the field of bad environments
Close and carry out washing and cleaning operation.4. Cleaning by High Pressure Water Jet is quick, thorough.For example:The clear and coherent rate of sewer pipe is 100%, peace and quiet rate
For more than 90%；The peace and quiet rate of heat exchanger is more than 95%；The descaling rate of boiler up to more than 95%, every comb of cleaning when
Between be 2~3 minutes.5. cleaning cost is low, and only about 1/3 or so of Chemical cleaning, i.e. Cleaning by High Pressure Water Jet, which belong to, carefully penetrates
Stream, it is continuous it is continual in the case of, water consumption is 1.8~4.5m3/h, and power is 35~90KW or so, belongs to energy-saving and sets
It is standby.6. Cleaning by High Pressure Water Jet is widely used.The position that every water jet can be directly mapped to, either pipeline and container intracavity,
Or equipment surface, regardless of being hard foulant, or solid tamper, it is departed from cohesive parent rapidly, it is thorough
Bottom is cleaned up.Cleaning by High Pressure Water Jet, without particular/special requirement, only requires water to equipment material, characteristic, shape and dirty species
Jet can reach.7. it is different from Chemical cleaning, the discharge of Cleaning by High Pressure Water Jet unharmful substance and problem of environmental pollution,
The air-borne dust concentration of operation area, environmental protection can also be reduced after water jet materialization.In summary, Cleaning by High Pressure Water Jet is clear
Effect is washed with there is unrivaled advantage in terms of efficiency, cleaning cost and environmental protection, its popularization and application is inexorable trend.
